100 Walla Walla Sweet Onion seeds, Allium cepa
This is the classic, large, overwintering onion of the Pacific Northwest, specifically Washington State. A very large, sweet, juicy onion with a mild flavor. Gets sweeter when cooked.
It can be planted in the spring if given a really early start indoors, or in August to overwinter. Spring planted Walla Walla sweet onion seeds result in bulbs that are not quite as mild as the overwintered ones. Spring sown Walla Walla onions may not size up as well.
This variety is hardy to -10° F. It is a long day onion, suitable for planting between the 35th and 55th parallels. It might not have good storage ability, but it makes beautiful caramelized onions! Onions grow well alongside beets, Brassicas, carrots, dill, kohlrabi, leeks, lettuce, strawberries and tomatoes. Don’t plant onions near asparagus or peas.
Matures in 150 days if spring sown; 300 days if fall sown.
